imagezero_transport 
ImageZero is a fast, lossless compression algorithm for 24-bit color photographic images developed by Christopher Feck. This repository repackages it as a catkin package, has a package that provides ROS integration, and has a package that implements a ROS image_transport plugin that uses it.
Packages
imagezero
The ImageZero image compression library, restructured into a catkin package. ImageZero is a high-performance lossless compression algorithm designed for natural photos.
imagezero_ros
A library that provides ROS integration for ImageZero. It contains methods for
using ImageZero to convert between sensor_msgs/Images and sensor_msgs/CompressedImages.
imagezero_image_transport
A ROS image_transport plugin that uses
ImageZero as its compression mechanism. It can be used like any other ROS
image_transport by setting the image_transport param for your client node to imagezero.
Building From Source (ROS Indigo, Jade, Kinetic)
These directions assume you have already set up a catkin workspace. See this tutorial on the ROS Wiki for help setting up a catkin workspace.
Checking out the source code (wstool)
If you're using wstool, add this repository to your wstool workspace:
wstool set imagezero --git https://github.com/swri-robotics/imagezero_transport.git -v 0.2.0
Checking out the source code (git)
If you're not using wstool, you can check out the repositories with git:
git clone https://github.com/swri-robotics/imagezero_transport.git
Installing dependencies and building
Install all of the dependencies using rosdep by running the following command from the root of your catkin workspace:
rosdep install --from-paths src --ignore-src
Build the workspace with catkin_make:
catkin_make
